A corrupt police detective enjoying semi-retirement in Tidewater Virginia stumbles onto an unsolved homicide that, given his nature, he'd be happy to leave unsolved. But a few people in his life have other ideas and drag him into an investigation that offers a chance for some small measure of redemption if he'll only take it. As murder squads go, this crew is no A Team — just an adolescent kid from up the block, a mouthy, conspiratorial-minded paraplegic, and an unhappy housewife our rotten cop met by chance in a Trader Joe's. What these three lack in savvy and expertise, they more than make up for in blundering determination, so Theory of the Case becomes the story of one man's trio of mongrel friends refusing to let him go on being what he's been.

The world T.R. Pearson is constructing just gets larger and larger.  The pleasures of entering it are irresistible
